Time Zone Converter
Source Time
Source UTC Offset
Target UTC Offset
A time zone converter calculates the local time in one location given another, using UTC offsets. UTC is the global reference; all time zones are offset from it.
- 1UTC time = Source local − Source UTC offset
- 2Target local = UTC + Target UTC offset
- 3DST shifts clocks +1h in spring; −1h in autumn
- 4Offsets range from UTC−12 to UTC+14
3:00 PM London (UTC+0) → Sydney (UTC+11)=3:00 PM + 11h = 2:00 AM next day Sydney time
| City | Standard offset | Summer (DST) |
|---|---|---|
| London | UTC+0 | UTC+1 (BST) |
| New York | UTC−5 | UTC−4 (EDT) |
| Dubai | UTC+4 | No DST |
| Singapore | UTC+8 | No DST |
| Sydney | UTC+10 | UTC+11 (AEDT) |
